Zhipu AI
BigModel's model overview lists CogVideoX-3 as a video-generation model and CogVideoX-Flash as a free model, with text, image and first/last-frame generation support depending on model.
Editorial verdict
Developers who need a Z.ai video-generation API inside the BigModel stack.
Compare Kling or Hailuo before using it for no-code creator workflows.
CogVideoX is a real BigModel API capability and should be tracked separately from ChatGLM.
Usage-based video API pricing varies by model
Free model where available, Platform billing
Commercial use should follow the current product, API, model license and billing terms.
Review prompt, file, media upload, retention and training-use terms before sensitive workloads.
Use it for text-to-video, image-to-video and first/last-frame API experiments.
Model names, quotas, release status, regional access and commercial terms can change quickly; recheck official sources before procurement or production use.
